Abstract

|
The purpose of the present study was to investigate the research trend in prosodic features of children and adolescents with autism spectrum disorders (ASD). For the objective of this research, peer-reviewed journals published between 2005 and 2012 have been selected and reviewed. Twenty-four studies which met the predetermined inclusion and exclusion criteria were reviewed in terms of participants, research methods, dependent variables, independent variables, results, and experimental trends. Results indicated that children and adolescents with ASD were significantly more impaired in prosodic features associated with stress, intonation, pitch, intensity, and duration. They were also more likely to rely on prosodic clues than other linguistic features. It was found in this study that the listener’s auditory perceptual judgment and the instrumental methods on their prosodic features revealed different results. Correlation analyses showed a significant association between prosodic ability, language ability and communication ability, while the association between pragmatic ability and prosodic ability was unclear. The theoretical and empirical implications of these findings were discussed along with some suggestions made for further research.
